Cardboard box



Oct. 31, 1939. .1. CALLMANDER CARDBOARD BOX Filed March 19, 1957 Patented Oct. 31, 1939 UNITED STATES PATENT OFFICE Application March 19, 1937, Serial No. 131,929 In Sweden August 30, 1933 3 Claims.

This invention refers to boxes of cardboard for lozenges, pills, and similar small pieces, and also for powders and grains; The box is preferably but not necessarily made of one single integral piece of cardboard.

More particularly, the invention refers to such boxes as consist of one single outer box having a closing flap integral therewith but having no displaceable inner box.

The chief object of this invention is torender a box of this type more simple, practical and hygienic than heretofore.

Another object of this invention is to render it possible totake the articles or objects from the box individually, without touching the articles or objects with the fingers.

Another object of this invention is to render it possible to take out the articles or objects of the box, while it is not necessary to open the flap fully (i. e. to pull the flap wide open).

Because the objects may be taken out separately, while there is no risk of the hand touching the adjacent objects in the box, the box is very hygienic in use. In spite of these advantages, the

box is inexpensive and simple.

Two embodiments of the box in accordance with this invention are shown in the annexed drawing. Fig. 1 shows the box in a perspective view, the closing flap being opened and the articles ready for sliding out. Fig. 2 shows the box in a developed state, i. e. laid out flat in a plane. Fig. 3 shows a perspective view of another embodiment. Fig. 4 shows the box of Fig. 8, as developed or flattened out upon a plane. Figs. 2

and 4 may be said to show the cutting for the box, before being folded and pasted.

Referring now to Figs. 1 and 2 of the drawing, I and 2 are the two wide side walls of the box body, while 3 and 4 are the narrow end walls at right angles thereto. As usual, the box is provided with a bottom, which is formed by the flaps 6, l and 8. Integral with the wall I, there is a side flap 5, which is pasted to the wall 4 after the cutting has been folded on the vertical lines 5 shown in the drawing. In similar manner the flaps 6, I and 8 are folded and pasted together to form the bottom of the box.

The closing flap 9 is considerably longer than those-generally used in such boxes and has three 50 folding lines H], ll, [2. The distance between the lines Ill and II is substantially equal to the breadth of the end wall 3 or 4. It is to be observed that the flap 9' is folded on the lines Ill, ll, l2 in the same sense, that is inwards, as is 55 evident from Fig. 1. The narrow end wall 3 has a lateral flap l3 which is considerably longer than those generally used in such boxes. In other words the flap I3 is substantially longer than the width of the wall 3. At'their corresponding edges l4 and IS the wall 4 and the flap 5 5 have no such lateral flap like l3.

This device is used as follows:

For taking out the lozenges or other objects packed in the box, the flap 9 is opened to a certain extent, as shown in Fig. l. The free edge 10 i6 of this flap still remains caught within the box and cannot spring out. .But the lateral flap will spring upwards to a certain degree, until checked by the flap 9. In order to take out the lozenges separately, the box should be inclined 15 so as to cause the opening between the flap 9 and the edges l4, I5 to be turned downwards. The elongated flap l3 prevents the lozenges from falling out at the other end of the box, in spite of the fact that the flap 9 is open.

Instead of being integral with the body of the box, the flaps l3 and 9 may consist of separate strips of cardboard pasted to the corresponding walls of the box.

In the embodiment shown in Figs. 3 and 4, a 25 portion of the flap 9 is cut away at I! so as to increase the size of the discharge opening. Between the lines in and II no part is cut away. In other respects this embodiment is similar to that shown in Figs. 1 and 2, and similar parts 30 carry similar reference characters in all of the figures.

In my United States Patent No. 2,090,723 for Boxes for cigarettes and similar oblong articles a box is claimed having a single lateral flap along 35 which the cigarettes may slide out individually, after a closing flap has been entirely drawn out of the box.

What I claim is:

1. In a parallelopipedic single box for small ob- 40 jects, without any displaceable inner box, in combination, two parallel broad side walls, two narrow end walls parallel to each other and at right angles to said broad side walls, a bottom at right angles to said side walls and to said end walls, a closing flap attached to the edge of one of said side walls at the top end thereof which is opposite to said bottom, said closing flap being flolded thnce in the same direction and turned inwards into the box to close the top end thereof, and one single lateral flap attached to only one of said end walls at the top end thereof which is opposite to said bottom, said lateral flap being normally below the inturned closing flap and being longer than the width of said end walls, 66

while said closing flap is so long that its free edge remains within the box after the closing flap has been drawn out sufliciently to permit said objects to slide out individually at that edge of said closing flap which is remote from said lateral flap.

2. In a parallelopipedic one-piece cardboard box for lozenges and similar small articles, in combination, two parallel broad side walls, two parallel narrow end walls at right angles to said side walls, a bottom at right angles to said side walls and said end walls, a closing flap attached to the'edge of one of said side walls at the top end thereof which is opposite to said bottom, said closing flap being folded thrice in the same direction and bent inwards into the box to close the top end thereof, and one single lateral flap attached to only one of said end walls at the top end thereof which is opposite to said bottom, said lateral flap being normally folded below sald closing flap and longer than the width of said end walls, while said closing flap is so long that its free edge remains within the box, even after the closing flap has been drawn out partially to permit said articles to slide out individually at an opening formed at that edge of said closing flap which is remote from said lateral flap, which has a part thereof cut away at that edge.

8. In a parallelopipedic single cardboard box for lozenges and similar small objects, without any displaceable inner box, in combination, two parallel broad side walls, two narrow end walls parallel to each other and at right angles to said broad side walls, a bottom at right angles to said side walls and said end walls, a closing flap attached to the edge of one of said side walls at the top end thereof which is opposite to said bottom, said closing flap being folded in the same direction on three lines of folding and. turned inwards into the box to close the top end thereof, a part of said closing flap being cut away at one lateral edge thereof between the middle line of folding and the free edge of said closing flap, and one single lateral flap attached to the top end of that one of said end walls which is remote from said cut-away portion of said closing flap, said lateral flap being normally below the inturned closing flap and being longer than the width of said end walls, while said closing flap is so long that its free end remains within the box 'even after said closing flap has been pulled out to a certain extent sufilcient to permit said objects to slide out separately by gravity.
